Originally posted by Cuthbert No, YOU don't understand the simple fact you can't judge the sharpness of a lens from a post processed image. Or any other optical qualities for the simple reason you are adding other parameters that modify (enhances?) the quality of the glass.
For the process of going from negative to digital, as said before IMO it should be as transparent as possible especially if you want to appreciate the other factors: light, lens, exposure (from the camera), film. From an engineering perspective if we have to define what is called "transfer faction" its value should be as equal to 1 as possible, it's the same principle of the calibration of the sensors used on a telemetry, you add digital things to the signal, but you want them less invasive as possible.
However talking about the M50 mm f1.4 if we want to judge its sharpness in the centre, bokeh and contrast wide open these UNprocessed pictures don't lie:
If we want to judge its behaviour stepped down to get as much DOF as possible perhaps this picture (Coltonpicture?) might be of help:
Cuthbert, this is the last I'll post on it becasue it's getting boring. I also like your photograpahy, and understand your intent about showing the true qualities of equipment and film. In no way is this meant to be personal, but unlike audio,
all digital images have an element of sharpening and colour interpretation. Just because this was done in an automated fashion, by a minicab scanner (or such like), you cannot deny that it happens!
Now I know sharpening ("post-processing") etc can be over-done, but that is predominantly a matter of taste... I would understand your argument a lot more if you were trying to compare scanned and printed photos against optically produced prints - but you're not: all the images on this thread are digital, and therefore have been interpreted by some sort of 'ADC'.
Anyway, no hard feelings!
